The electronic device 80 may includean Internet protocol television (IPTV), a personal computer (PC), apersonal digital assistant (PDA), and a smart phone.

Hereinafter, operation of the navigation system according to a firstexemplary embodiment of the present invention will be described indetail.

FIG. 4 is a flowchart illustrating operation of a data server accordingto a first exemplary embodiment of the present invention, FIG. 5 is aflowchart illustrating operation of an electronic device according to afirst exemplary embodiment of the present invention, and FIG. 6 is aflowchart illustrating operation of a navigation device according to afirst exemplary embodiment of the present invention.

Hereinafter, for convenience of description, it is assumed that theelectronic device is an IPTV and the network 30 is Internet. Further, itis described as the video output unit 310 includes a display device.

Referring to FIGS. 4 and 5, operation of the IPTV 80 and the data server70 will be first described.

The IPTV 80 is connected to the data server 70 according to a userrequest (S102). The IPTV 80 is connected to the data server 70 throughan Internet web browser. The IPTV 80 transmits first identificationinformation to the data server 70 (S104). Accordingly, the data server70 receives the first identification information (S106). The firstidentification information may be a user ID for connecting to the dataserver 70, or may be an intrinsic identification number given to theIPTV 80.

In order to receive the user ID, the user can input a user descriptionand identification information such as a social security numbernecessary for the data server 70. In this case, the user caninput/register together second identification information of the mainlyusing navigation device 10.

The second identification information may be a serial number of thenavigation device 10 or an identification number given to the networkcommunication unit 120. The first identification information may be usedfor authentication of the user or the electronic device.

The IPTV 80 provides a user interface such as a graphical user interface(GUI) that can receive an input of user input information (S108).Thereafter, the IPTV 80 receives an input of the user input informationusing the GUI (S110). The user input information may be input by theuser input device 83. The user input information may include a startingpoint, a destination point, a passing point, and an essential passingsegment.

The GUI may be provided by a navigation application for appropriatelyreceiving an input of the user input information necessary for formingpath setting information according to the present invention from theuser. The navigation application is provided by the data server 70 andis driven on Web. Alternatively, the navigation application is stored atthe IPTV 80 and may be driven in the IPTV 80. The navigation applicationprovides the GUI and includes path search algorithm that searches for apath based on the user input information.

Thereafter, the IPTV 80 transmits the user input information to the dataserver 70 (S112). The data server 70 receives the user input information(S114). The data server 70 acquires a moving path (hereinafter, movingpath information) from the starting point to the destination point basedon the user input information (S116). In order to acquire the movingpath information, the data server 70 can use various path searchalgorithm. For example, as described above, various path searchalgorithm according to a search condition such as a shortest path, anoptimal path, and a shortest time path may be used for acquiring themoving path information. In this case, the user can select algorithm tosearch for a path. Alternatively, the user may select one of a pluralityof moving paths acquired using a plurality of algorithm. The moving pathinformation may be acquired from the IPTV 80 according to a case.

Hereinafter, reception of an input of the user input information will bedescribed.

FIGS. 7 to 10 are diagrams illustrating screens that receive user inputinformation according to a first exemplary embodiment of the presentinvention.

The user can input a starting point, a destination point, and a passingpoint. Accordingly, the data server 70 or the IPTV 80 acquires apreliminary moving path PR according to the input information anddisplays the preliminary moving path PR together with a map image in thedisplay device 82 of the IPTV 80. When the user has a segment wishing toessentially pass (hereinafter, an essential passing segment) unlike thepreliminary moving path PR, the user can input an essential passingsegment R1 through the user input device 83. As shown in FIG. 9, inorder to set the essential passing segment R1, the user can use a methodof directly changing some segment of the preliminary moving path PRthrough an input device such as a touch screen or a mouse in order topass through other segments. Alternatively, as shown in FIG. 10, theuser may set the essential passing segment R1 by inputting a road nameof the essential passing segment. In addition, various user interfacesfor receiving an input of the essential passing segment R1 may beprovided.

The user input information may include additional interest information.The additional interest information may be information about good tasterestaurants, information about historical archaeological sites, andinformation specially interested and registered by the user. Theadditional interest information may be information normally specifiedand stored by the user as additional interest information, and may beinformation separately input while inputting the user input information.The additional interest information may include a position coordinate ofa corresponding region and various information of the correspondingregion. For example, after a user reads an article about‘Mongchontoseong’ the user may register the article as additionalinterest information. Alternatively, the additional interest informationmay be selected from information provided from the data server 70. Forexample, the data server 70 provides information about variousrecommended tourist sites, good taste restaurants, and historicalarchaeological sites at a periphery of a moving path acquired by theuser input information, and the additional interest information may beinformation selected from the above information by the user. Theadditional interest information may be appropriately provided to theuser through the navigation device 10.

This will be described later.

Although not shown in the drawings, the navigation application mayprovide trial driving information. For example, the navigationapplication may provide simulation drive like actual driving accordingto the preliminary moving path PR or the acquired moving pathinformation.

Accordingly, the user can add or adjust the user input information.

Referring again to FIGS. 4 and 5, when the user input information isreceived (S114) and the moving path information is acquired (S116), thedata server 70 generates path setting information based on the userinput information and the acquired moving path information (S118). Thedata server 70 generates title information corresponding to the pathsetting information together with the path setting information (S118).

The path setting information includes a destination point input by theuser input information. The path setting information may further includeat least one of the passing point, the essential passing segmentinformation, and the acquired moving path information. Further, the pathsetting information may further include the additional interestinformation.

The title information may be generated by the data server 70 based onthe destination point and the passing point. For example, when it isinput as the destination point is ‘A’ and the passing point is ‘B’, thetitle information may be generated like a ‘path for the destinationpoint A via the passing point B’. Further, the title information may begenerated to reflect a date and time point in which the user inputinformation is input to the title information. The title information maybe generated by other various methods. Alternatively, the titleinformation is the user input information and may be directly input bythe user through the IPTV 80.

The data server 70 stores the generated path setting information and thetitle information (S120).

The path setting information and the title information may be matched tothe first identification information and be stored.

Hereinafter, operation of the navigation device 10 and the data server70 will be described with reference to FIGS. 4, 6, and 11.

FIG. 11 is a diagram illustrating operation of a navigation device forreceiving path setting information according to a first exemplaryembodiment of the present invention.

Referring to FIGS. 4 and 6, the navigation device 10 is turned onaccording to a predetermined signal (S122). When the navigation device10 is turned on, the navigation device 10 is connected to the Internet30 (S124), as described with reference to FIG. 1. A connection of thenavigation device 10 to the Internet 30 may be performed by a userrequest or may be automatically performed by interlocking with thetum-on operation. For example, as shown in FIG. 11A, the navigationdevice 10 displays an initial screen together with a tum-on operation,and as shown in FIG. 11B, the navigation device 10 is connected to theInternet 30 by interlocking with the tum-on operation and displays astandby screen for transmitting and receiving various necessary data toand from the data server 70, as described later. The navigation device10 is connected to the data server 70 through the Internet 30 (S126).

The navigation device 10 requests path setting information to the dataserver 70.

A request for the path setting information may be performed by thefollowing series of operations.

First, the navigation device 10 transmits second identificationinformation related to the navigation device 10 to the data server 70(S128). The second identification information may be an intrinsicidentification number (e.g., serial number of the navigation device) ofthe navigation device 10 and may be an intrinsic identification numberrelated to the network communication unit 120 of the navigation device.Alternatively, the second identification information may be an intrinsicidentification number given to the storage unit 400 of the navigationdevice 10. Alternatively, the second identification information may beintrinsic identification information given to the user, which ispreviously stored at the navigation device 10. The second identificationinformation may be used for authenticating the user or the navigationdevice 10.

Thereafter, the navigation device 10 requests transmission of the numberof path setting information matching to the second identificationinformation and title information corresponding thereto (S130).

The data server 70 receives the request (S132), and the data server 70searches for path setting information corresponding to the secondidentification information (S134).

In this case, in order to search for path setting information matchingto the second identification information, the data server 70 searchesfor the first identification information corresponding to the secondidentification information. A search of the first identificationinformation corresponding to the second identification information canbe performed based on the second identification information registeredwhen registering a user ID, as described above. Alternatively, a searchof the first identification information corresponding to the secondidentification information may be performed by searching for registereduser information of the navigation device 10 by the secondidentification information and searching for first identificationinformation corresponding to the user information among the firstidentification information. For example, identification informationgiven to the network communication unit 120 may include informationabout a user of the network communication unit 120, and the data server70 may search for the first identification information matching theretousing information about the user.

The data server 70 transmits the found path setting information andtitle information corresponding to the found path setting information tothe navigation device 10 according to the search result (S136). In thiscase, the data server 70 may transmit the number of the path settinginformation together with the found path setting information and thetitle information. The data server 70 may transmit the number of thefound path setting information and/or title information according to arequest of the navigation device 10, as described above, but maytransmit the found path setting information itself to the navigationdevice 10.

The navigation device 10 receives the title information and/or thenumber of the found path setting information (S138) and determineswhether the number of the found path setting information is plural(S140).

If the number of the found path setting information is plural, thenavigation device 10 selects to receive which information of a pluralityof path setting information according to a predetermined signal (S142).For example, as shown in FIG. 11C, the navigation device 10 may displaythe received title information in the display device 310 and thus theuser can select path setting information to receive based on the titleinformation. The navigation device 10 may select one of the plurality ofpath setting information according to predetermined selection algorithm.For example, the navigation device 10 may select most recently generatedpath setting information.

Alternatively, the navigation device 10 may select path settinginformation generated based on most recently input user inputinformation.

If the path setting information is one, the navigation device 10determines whether a selection of the user to receive the found pathsetting information is received (S144), as shown in FIG. 11D. If theuser selects not to receive the path setting information, the navigationdevice 10 is converted to a general path search mode (S146). Forexample, the navigation device 10 may receive a direct input of the userfor a destination point and/or a passing point, search for a guidancepath R, and guide the guidance path R to the user.

If a plurality of path setting information is searched for, thenavigation device 10 requests to transmit one path setting informationselected from the plurality of path setting information to the dataserver 70, or if one path setting information is searched for andreception of the found path setting information is requested by theuser, the navigation device 10 requests to transmit the found one pathsetting information to the data server 70 (S148). Hereinafter, forconvenience of description, both path setting information selected froma plurality of path setting information and one path setting informationin which reception is requested is referred to as selected path settinginformation.

The data server 70 receives the request (S150) and transmits theselected path setting information to the navigation device 10 (S152).The navigation device 10 receives the selected path setting information(S154) and acquires a user moving path based on the received pathsetting information (S156). The user moving path can be acquired by apredetermined application stored in the navigation device 10.

Step S156 of acquiring the user moving path can be performed by variousmethods. For example, when the moving path information is included inthe path setting information, the navigation device may acquire the usermoving path identical to the moving path information. When the passingpoint is included in the path setting information, the navigation device10 can acquire the user moving path to surely pass through the passingpoint. When the essential passing segment is included in the pathsetting information, the navigation device 10 can acquire the usermoving path to surely pass through the essential passing point.

FIG. 12 is a diagram illustrating a navigation device for providing aguidance path according to an exemplary embodiment of the presentinvention.

Referring to FIG. 12, after the navigation device 10 acquires the usermoving path, the navigation device 10 sets the user moving path as theguidance path R and appropriately guides the guidance path R to adestination OP to the user by interlocking with a present position CPreceived through the position check unit 110.

FIG. 13 is a flowchart illustrating a method in which a navigationdevice displays additional interest information according to a firstexemplary embodiment of the present invention, and FIG. 14 is a diagramillustrating a navigation device for displaying additional interestinformation according to a first exemplary embodiment of the presentinvention.

Referring to FIG. 13, when additional interest information is includedin the path setting information, the navigation device 10 guides a path(S158), and the navigation device 10 determines whether a distancebetween a position corresponding to additional interest information anda present position of the navigation device 10 is a predetermineddistance D or less (S160), and if a distance between a positioncorresponding to additional interest information and a present positionof the navigation device 10 is a predetermined distance D or less, thenavigation device 10 displays various information stored as theadditional interest information through the display device 310 (S162).

For example, when information about ‘Mongchontoseong’ is registered asthe additional interest information and a position of the navigationdevice 10 exists within a predetermined distance from ‘Mongchontoseong’,various information registered by the user for ‘Mongchontoseong’ may bedisplayed through the display device 310, as shown in FIG. 14. In thiscase, a screen of the display device 310 may be partitioned into a pathguidance screen and an additional interest information display screen.

The additional interest information may include video, image, and audioinformation in addition to a text. When the additional interestinformation includes audio information, the additional interestinformation may be output through the audio output unit 320.

When transmission/reception of data is complete from the data server 70,the navigation device 10 releases a connection to the Internet 30. Forexample, after the navigation device 10 receives the path settinginformation from the data server 70 (S154), a connection of thenavigation device 10 to the Internet 30 may be released. Thereby, a costfor transmission/reception of data can be minimized.

Hereinafter, operation of the navigation system according to a secondexemplary embodiment of the present invention will be described indetail.

FIG. 15 is a flowchart illustrating operation of a navigation deviceaccording to a second exemplary embodiment of the present invention.FIG. 16 is a flowchart illustrating operation of a data server accordingto a second exemplary embodiment of the present invention. FIG. 17 is aflowchart illustrating operation of an electronic device according to asecond exemplary embodiment of the present invention.

Referring to FIG. 15, operation of the navigation device 10 according toa second exemplary embodiment of the present invention will bedescribed.

The navigation device 10 determines whether an actual moving path of thenavigation device 10 deviates from a preset guidance path R whileguiding the path (S202), and if an actual moving path of the navigationdevice 10 deviates from a preset guidance path R, the navigation device10 stores the actual moving path at the storage unit 400 (S204). Whenstoring the actual moving path, the navigation device 10 can storetogether a separation position and/or a separation time point, whichare(is) a position and/or a time point in which the actual moving pathdeviates from the path. The preset guidance path R may be acquiredaccording to the first exemplary embodiment of the present invention.

The navigation device 10 transmits the stored actual moving path to thedata server 70 (S206). In this case, the separation position and/orseparation time point may be transmitted together.

Hereinafter, the actual moving path, the separation position, and theseparation time point are referred to as user actual moving pathinformation. Second identification information, which is identificationinformation related to the navigation device 10 together with the actualmoving path information may be transmitted to the data server 70.Further, when the guidance path R is acquired according to the firstexemplary embodiment of the present invention, the path may be alsotransmitted as identification information (e.g., the title information)about some path setting information.

The navigation device 10 transmits the user actual moving pathinformation to the data server according to a predetermined timeinterval. Alternatively, when a tum-off signal of the navigation device10 is received, before the navigation device 10 is turned off, thenavigation device 10 may transmit the user actual moving pathinformation to the data server 70. Alternatively, when the presentposition is at a periphery of a destination point, the navigation device10 may transmit the user actual moving path information to the dataserver 70. When a connection between the navigation device 10 and theInternet 30 is released, in order to transmit user actual moving pathinformation to the data server 70, the navigation device 10 may beconnected to the data server 70 by connecting to the Internet 30.

Although not shown in the drawings, the navigation device 10 may storeeco-driving information at the storage unit 500. The eco-drivinginformation is information for determining whether a vehicle in whichthe navigation device 10 is installed economically drives by apredetermined reference.

For example, the eco-driving information may include information aboutan overspeed/low speed of the vehicle at a predetermined economy speedsegment. The eco-driving information may include information about rapidacceleration/rapid retardation of a predetermined economy acceleration.

The eco-driving information may be transmitted to the data server 70,similarly to the user actual moving path information, and the dataserver 70 may store the eco-driving information. In this case, theeco-driving information may be accumulatively stored to correspond tothe first identification information or the second identificationinformation. When a request through the IPTV 80 exists, the eco-drivinginformation stored at the data server 70 may be transmitted to the IPTV80, the IPTV 80 may be provided the eco-driving information to the user.Further, the eco-driving information may be appropriately statisticallyprocessed and stored at the data server 70, or the eco-drivinginformation may be formed in a graphic or in a pattern based on thestatistically processed eco-driving information and may be stored at thedata server 70. The statistically processed or graphically formedeco-driving information or the eco-driving information formed in apattern may be transmitted to the IPTV 80, and the IPTV 80 can providethe statistically processed or graphically formed eco-drivinginformation or the eco-driving information formed in a pattern to theuser.

Referring to FIGS. 16 and 17, operation of the data server 70 and theIPTV 80 according to a second exemplary embodiment of the presentinvention will be described.

The data server 70 receives the user actual moving path information(S208). The data server 70 stores the user actual moving pathinformation (S210). The user actual moving path information may bestored to correspond to the second identification information and/or thefirst identification information matching to the second identificationinformation. Alternatively, the user actual moving information may bestored to correspond to identification information of the transmittedpath setting information. The data server 70 provides the user actualmoving path information to the IPTV 80 according to a predeterminedsignal (S212).

After the IPTV 80 receives the user actual moving path information(S214), the IPTV 80 displays an actual moving path included in the useractual moving path information in the display device 82 (S216). StepS214 of receiving the user actual moving path information can beperformed by a separate request of the user or by interlocking with atum-on operation of the IPTV 80. For example, when the IPTV 80 isturned-on, the most recent information corresponding to the firstidentification information related to the IPTV 80 may be received fromthe data server 70. Further, as described above, the IPTV 80 may bereceived the eco-driving information.

Thereafter, the IPTV 80 receives a selection of a use attribute of theuser actual moving path from the user (S218). For example, the IPTV 80may receive a selection from the user about whether to ignore the actualmoving path, to use the actual moving path in order to update the movingpath information according to the first exemplary embodiment of thepresent invention, to store the actual moving path as a user intrinsicpreference path, or to share the actual moving path with other users.

The IPTV 80 transmits an appropriate processing signal of the actualmoving path to the data server 70 according to a selection of a useattribute of the actual moving path (S220). The data server 70appropriately processes the user actual path information according toreception of the processing signal.

For example, when a selection to ignore the actual moving path isreceived, the IPTV 80 may transmit no signal to the data server 70 orrequest deletion of the user moving path information.

The data server 70 deletes the user actual path information according tothe deletion request.

When the actual moving path is selected to use for update of the movingpath information, the IPTV 80 requests to store the actual moving pathto the data server 70. In this case, the data server 70 replaces themoving path information included in the path setting information withthe actual moving path according to the request and stores the actualmoving path. Accordingly, when the same path setting information isselected later and transmitted to the navigation device 10, the movingpath information that may be included in the path setting information isupdated to the actual moving path and is transmitted to the navigationdevice 10.

When it is selected to use the actual moving path as a user intrinsicpath, the IPTV 80 transmits an appropriate signal thereof, and the dataserver 70 can store the actual moving path as a path for a startingpoint and a destination point used for setting of the guidance path R.Accordingly, when the data server 70 is connected to the IPTV 80 or thenavigation device 10, if the starting point and the destination pointare input, in order provide the stored actual moving path as theguidance path R, the data server 70 can update path search algorithmprovided in the IPTV 80 and/or the navigation device 10.

When it is selected to share the actual moving path with another user,the IPTV 80 transmits an appropriate signal thereof, and the data server70 can separately store the actual moving path in order to share theactual moving path with other users.

Although not shown in the drawings, the data server 70 can use the useractual moving path information for algorithm for providing an optimalpath to the user. For example, the data server 70 may accumulativelystore the user actual moving path information and provide an optimalpath through statistic calculation of an accumulated separation timepoint and an accumulated separation position included in the user actualmoving path information. That is, at a similar time zone and a similarsegment, when the user deviates from a preset path, the data server 70determines the segment as a traffic jam segment at the time zone.Therefore, when searching for the segment at the time zone, the dataserver 70 may reflect the information to the algorithm not to passthrough the segment, if possible. Further, for the found path of thesame starting point and the same destination point, when it isdetermined that an actual moving segment different from the found pathpasses through the same segment several times, the segment is determinedas a user's preference path and hen when the segment is searched for,the algorithm can be updated to search for a path by reflecting theuser's preference path.

The updated path search algorithm may be reflected to a navigationapplication stored at the IPTV 80 and may be reflected to path searchalgorithm of the navigation device 10.

By the present invention, the user can receive path guidance using thenavigation device 10 through a minimum manipulation. For example, whenpath setting information is one, the user may receive a guide of adesired path with only a selection operation about whether to receivethe path setting information. Even when a plurality of path settinginformation exists, the user may receive a guide of a desired path withonly one operation of selecting one of displayed title information.Thereby, manipulation convenience of the navigation device 10 canincrease and accident dangerousness can be reduced due to a manipulationof the navigation device while driving.

Further, by the present invention, the user can easily plan a triptogether with families or acquaintances at a home. For example, the usercan efficiently select a tourist site (a destination point and a passingpoint) by connecting to the data server 70 having various data using anIPTV or a PC at a home and specifically plan a trip by searching for apath to the tourist site and performing trial driving thereof. Further,by registering/inputting various additional interest information(historical archaeological sites, good taste restaurants, recommendationtravel sites, etc.) around the found path as the user input information,when actually traveling, additional interest information can be providedthrough the navigation device and thus a boring moving time to adestination point can be usefully used.

Although exemplary embodiments of the present invention have beendescribed in detail hereinabove, it should be clearly understood thatmany variations and modifications of the basic inventive concepts hereindescribed, which may appear to those skilled in the art, will still fallwithin the spirit and scope of the exemplary embodiments of the presentinvention as defined in the appended claims.
